The no-show socks that I wear with all of my slip-on sneakers are on sale for under $4 (reg $9.50) for a 2 pack + free shipping! Just use promo code CYBER at checkout. These are still very thin, but just a tiny bit thicker and better quality than the PEDS that I also love. (commissioned links) P.S. Grab some for a stocking.
